GSTN Multistate Registration: How to Get GST Registration in Multiple States at Once
The Goods and Services Tax Network (GSTN) launched a Multistate Registration facility on the GST portal on 1 October 2026. Normal (regular) taxpayers can now apply for GST registration in several States/UTs simultaneously under a single PAN, eliminating the repetitive filing of Form REG‑01 for each jurisdiction.
Key point: The Multistate Registration facility lets normal taxpayers obtain GSTINs for multiple states in a single portal session, saving time and avoiding duplicate data entry.

What Changed
Under the new workflow, the applicant selects all required States/UTs, generates a Master Tax Registration Number (TRN), and fills the common registration information once. The system then creates individual TRNs for each jurisdiction, pre‑filled with the common data. State‑specific details—principal place of business, Aadhaar authentication, and local documents—are completed separately for each individual TRN.
Who Is Affected
The facility is currently limited to Normal Taxpayers (regular GST registrants). It does not cover:
- Composition scheme taxpayers
- Casual taxable persons
- Non‑resident taxable persons
Businesses that stand to gain the most include:
- Manufacturers with plants or warehouses across states
- Service providers (IT, logistics, staffing) with multi‑state branches
- E‑commerce sellers or marketplace vendors required to register in every state where they fulfil orders
- Start‑ups and MSMEs scaling pan‑India
Practical Impact for Your Business
Consider a company that needs GSTINs in five states. Previously it would file five separate REG‑01 forms, re‑entering the same promoter and business details each time and uploading identical documents five times. With Multistate Registration:
- Common data is entered once under the Master TRN.
- State‑specific documents are uploaded only for the respective TRNs.
- The overall processing time shrinks dramatically, especially for businesses with standardized principal place‑of‑business setups.
Critical reminder: The Master TRN expires after 15 days. If the common information is not submitted within that window, the Master TRN is cancelled and the entire process must be restarted. Prepare all promoter PANs, Aadhaar numbers, and principal‑place‑of‑business details for each state before initiating the application.
Steps to Take Now
- Log in to the GST portal (www.gst.gov.in) → Services → Registration.
- Choose “New Registration” and select the Multistate Registration option.
- Select all required States/UTs and generate the Master TRN.
- Within 15 days, complete the common registration information – business details, promoter PANs, nature of goods/services.
- For each State/UT, fill state‑specific details – principal place of business address, local activity description, supporting documents (rent agreement, utility bill, ownership proof), and Aadhaar authentication of promoters.
- Submit each individual TRN and note the ARN (Application Reference Number) for tracking.
- Respond promptly to any queries from the GST officer as per Rule 9 of the CGST Rules.
If you already hold GSTINs in some states and wish to add more, consult your CA to determine whether the Multistate facility or a separate application is more appropriate.
Illustrative Example
Example: A Pune‑based IT services firm (annual turnover ₹18 crore) currently has a GSTIN for Maharashtra. It plans to open offices in Karnataka, Telangana, and Delhi. Under the old system, it would file three separate REG‑01 forms, each requiring the Managing Director’s Aadhaar authentication and re‑entry of promoter details. Using Multistate Registration, the firm selects the three states, generates a Master TRN, enters the common data once, and then uploads the local office lease agreements for each state separately. The time saved is material, and the risk of inconsistent data across applications is eliminated.

Frequently Asked Questions
Can a composition scheme taxpayer use the Multistate Registration facility?
No. The October 1 2026 advisory limits the Multistate Registration facility to Normal (regular) taxpayers. Composition scheme taxpayers must continue filing separate REG‑01 applications for each state.
Is the Multistate Registration facility available for first‑time GST registrations?
The advisory describes the facility as a way to apply in several States/UTs in one session under a single PAN. It does not restrict the feature to existing registrants, but you should verify the portal flow before starting a first‑time registration.
What documents are required for each state under the Multistate Registration facility?
Common documents (PAN of the business, promoter identity and address proof) are uploaded once with the Master TRN. For each individual State/UT TRN you must upload state‑specific proof of Principal Place of Business (rent agreement, utility bill or ownership proof) and complete Aadhaar authentication of the promoters.
Does this advisory change the legal requirement to register in each state separately?
No. Section 22 of the CGST Act still requires a separate GSTIN for every state where taxable supplies are made. The advisory only simplifies the *application* process; the statutory requirement remains unchanged.
What happens if the Master TRN expires before I complete the application?
The Master TRN lapses after 15 days. If the common information is not submitted within that period, the Master TRN is cancelled and you must restart the multistate registration process.
How long does the Master TRN remain valid after generation?
The Master TRN is valid for **15 days** from the date of issue. All common registration details must be entered within this window, otherwise the TRN is cancelled.
Can an existing GSTIN holder add new states using the Multistate Registration facility?
Yes. Existing registrants can generate a new Master TRN for additional States/UTs, enter the common data once, and then complete the state‑specific sections for each new jurisdiction.
Are there any additional fees for using the Multistate Registration facility?
The advisory does not mention any extra fees. The standard GST registration fees, if applicable, continue to apply per State/UT as per the CGST Act and Rules.
